Why can't you use the down tubes with staggered? I put down tubes on my 37 QuadStep Outerlimits, they work well, I DID have to cut 4 inches off them so they were not as deep in the water. When the downtubes were full length, with the staggered #6 drives, they were blowing straight down on top of the front of the steering and water was deflecting into them, with the 4 inches cut off they're mint !

I use the CMI mufflers in my Gladiator with stock 500's and 5" exhaust. It brought the noise down to 91 Db from alot more than that. Best part was the 30 minute install and only about a 1 mph loss at top speed

Kaama it was in GH, on wensday, they gave me a repair and report. I was hoping somebody running 950 to 1000 hp was already running this mufflers so I could buy with and know they will work.
